Bose A30 Aviation Headset

The A30 Aviation Headset is the evolution of the A20. Its sleek, modern design significantly improves long term comfort with a lower on-head weight and reduced clamping force. It also features three modes of active noise reduction and tap control for talk-through communication.

The A30 upholds the acclaimed noise reduction and state-of-the-art materials and electronic capabilities of the A20. Each of these advancements helped create the best combination of noise reduction and audio clarity on the market.

Yes. Similar to the A20, there are left and right sensitivity adjustment wheels on the control module. These can be used to accommodate differential hearing loss and multiple radio inputs in stereo mode or to help users control radio inputs in one ear to hear outside sound sources more clearly. For larger adjustments, volume tuning is typically done on the audio panel or for each radio.

Yes. The A30 is optimized for use in general, military, and commercial aviation aircraft. It can be used in both fixed-wing aircraft and in helicopters. It can be purchased with different connection options, including Dual G/A, 6-pin LEMO and 5-pin XLR. The A30 is not recommended for open-cockpit aircraft where the headset is in the direct path of the wind and slipstream.

The Bose A30 comes in many variations, and customers can choose different configurations based on connector, cable, microphone, and module (Bluetooth or non-Bluetooth). The most popular aircraft connection option is dual G/A, but flexible power versions with auto-on capabilities are also available in 6-pin and 5-pin XLR configurations.

The most common connection configurations are:

• Dual plug (PJ 068 and ¼ inch stereo): With the dual plug, two AA alkaline batteries provide a minimum of 45 hours of operation while flying. This version is user-configured for stereo or mono audio and is commonly used across all aircraft types.
• XLR 5-pin: This configuration, often called the Airbus plug, is a mono connection that’s powered by the aircraft or batteries, depending on the aircraft’s capabilities. When disconnected, the flexible power feature allows pilots to switch seamlessly between aircraft and battery power.
• U-174: The U-174 is a single-plug configuration commonly used in both military aircraft and several helicopter models.
• (LEMO) 6-pin connector: With this option, the headset is connected to the aircraft via a 6-pin connector and is powered directly from the aircraft. Two AA alkaline batteries can also be used to enhance flexibility. When disconnected, the flexible power feature allows pilots to switch seamlessly between aircraft and battery power.*

*Bose adapters are available to convert a 6-pin connector to either a dual G/A plug or a U-174 for additional connection flexibility.

Yes. The integrated boom mic and cable can be attached to either side of the headset with the toolless connector mechanism in a few simple steps.

The Bose A30 Aviation Headset has multiple built-in equalization circuits. The primary ICS/radio communications path is designed to meet the latest TSO standard and to optimize voice intelligibility. An additional active EQ helps optimize the experience through the secondary (Bluetooth) audio path for wireless audio sources.

The Bose A30 Aviation Headset provides three modes of user selectable noise cancellation that were individually engineered for specific use cases. “Low” helps optimize interpersonal communication outside the use of an intercom system. “Medium” provides the most consistent amount of reduction across a wide range of frequencies, and “High” provides the most active noise reduction to maximize the signal-to-noise ratio for radio communication. All three modes have been engineered for distinct uses.

Bose does not make claims about the mode of noise reduction. We encourage pilots to try the product in a variety of aircraft to experience the dramatic performance and capability of each mode for themselves.

Overall, the Bose A30 Aviation Headset is one of the smallest, lowest-clamping, and lightest around-ear active noise cancelling headsets on the market — it’s a balance of function and comfort without sacrificing stability.

The headset’s angled earcups follow the contours of pilots’ heads, and the intentional shape of the headband pads help achieve the highest level of comfort in the lowest possible on-head weight. Additionally, the A30 has distinct left and right earcups with a quick release and a side swappable mic for improved comfort and ergonomics.

The A30 uses a noise cancelling electret microphone (often called a high-impedance microphone), which is typical for aircraft. It is optimized to reject far-field noise and improve performance when used with “hot mic” systems. A 5-ohm and a 150-ohm dynamic microphone are available in specific configurations.

The A30 operates for a minimum of 45 hours from two AA alkaline batteries in typical aircraft noise. With continuous operation of the Bluetooth function, battery life will last 25-plus hours. As always, battery life varies with the type of battery, noise environment, and features used during flight. The headset has a battery life indicator light to signal when batteries need to be replaced.

No. The control module can be used only with the model for which it was built. Although some of the cushions and parts may be forced onto the Bose A30 Aviation Headset, they were not designed for this product.

Yes. Bose offers replacement parts for its aviation headsets, including ear cushions, microphone windscreens, and cable assemblies. These replacement parts ensure your headset continues to function at its best and can extend the lifespan of your headset.

Bose aviation headsets feature advanced noise cancellation technology that uses microphones to detect ambient noise and cancel it out before it reaches the ear. This technology ensures clear communication and reduces the impact of engine noise, weather, and more on hearing.
